Extended Data Fig. 1: Supply cost curves split by region in TIAM-UCL.
a–c, Curves for oil (a), fossil methane gas (b) and coal (c). Costs are given on an energy-content basis (barrel of oil equivalent for oil, British thermal units for gas and joules for coal), on a US$2005 basis. For oil, different mining processes output different commodities (for example, oil sands mining initially (pre-upgrading) outputs a barrel of bitumen) hence the use of the energy-content cost basis. For gas, associated gas is not included in Extended Data Fig. 1b as it is a by-product of oil production
